Profiling the decidualisation response of women with endometriosis reveals diverse patterns of steroid responsiveness

Simitsidellis Ioannis , Gibson Douglas A. , Kelepouri Olympia , Horne Andrew W , Saunders Philippa T K

Endometriosis is a chronic hormone-dependent disorder, characterised by growth of ‘ectopic’ endometrial tissue outside the uterus. It has been reported that 30–40% of women who are sub/infertile have endometriosis. Infertility in women with severe endometriosis may be the result of either scarring or pelvic distortion, but in women with mild/moderate disease it is believed subfertility may result from disturbances in endometrial tissue function. Transformation o...

What is the impact of AR modulation in the decidualisation of hESCs from women with endometriosis?

Simitsidellis Ioannis , Gibson Douglas A. , Kelepouri Olympia , Horne Andrew W. , Saunders Philippa T. K.

Endometriosis is a hormone-dependent disorder, characterised by growth of endometrial tissue outside the uterus. It has been reported that 30–40% of women with infertility have endometriosis. Transformation of human endometrial stromal fibroblasts (hESC) (termed decidualisation) is accompanied by increased steroid synthesis and is fundamental to the establishment of a receptive endometrial microenvironment, which can support and maintain pregnancy. Evidence suggests that ...

Altering androgen precursor availability impacts on endometrial function

Gibson Douglas A , Kelepouri Olympia , Simitsidellis Ioannis , Critchley Hilary O D , Saunders Philippa T K

The establishment of pregnancy requires dynamic remodelling of the endometrium. Decidualization, a key part of this process, is characterised by differentiation of endometrial stromal fibroblasts (ESF) which secrete factors that regulate implantation and placental development. We recently discovered that ESF synthesise androgens which modulate the expression of endometrial receptivity and decidualization markers. Utilisation of the circulating androgen precursor DHEA within ta...

Androgen modulation of mouse uterus: a tissue-based bioassay for testing endogenous and synthetic androgen receptor modulators (SARMs)

Simitsidellis Ioannis , Kelepouri Olympia , Gibson Douglas A , Esnal-Zufiaurre Arantza , Saunders Philippa TK

The uterus is an androgen-responsive tissue and AR is expressed in cells within the endometrium and myometrium. We have demonstrated that treatment of ovariectomised mice with the potent androgen dihydrosterone (DHT) induces a uterotrophic response with changes in expression of genes involved in cell-cycle progression, Wnt signalling and an expansion of the glandular epithelium. Selective androgen receptors modulators (SARMs) are AR ligands in development as potential therapeu...
